The gang are on vacation!... again. While at Daphne's fathers timeshare, she swims right into a sea monster! While Velma doesn't want to vacation, this sure does give her something to do. But the monster doesn't seem to want anyone near the water, so how are they supposed to investigate? Within this chapter we learn about some activities the gang enjoy on their own time, some unfortunate things Shaggy has to deal with, and maybe even a secret of Velmas.
